Entry/Exit Lighting
The lamps inside the vehicle will go on when any door is
opened. These lamps fade out about 20 seconds after all
of the doors have been closed or when the ignition is
turned to ON/RUN. These lamps will also go on when
pressing the trunk release, unlock symbol, or the horn
symbol button on the Remote Keyless Entry System
(RKE) Transmitter.
After the key is removed from the ignition, the lamps
inside the vehicle stay on for about 20 seconds to
provide an illuminated exit.
Mirror Reading Lamps
The vehicle may have reading lamps on the rearview
mirror. Press the button near each lamp to turn the
reading lamps on and off.
Electric Power Management
This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery’s
temperature and state of charge and then adjusts
the voltage for best performance and extended life
of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or voltage display on the Driver Information Center (DIC),
you may see the voltage move up or down. This is
normal. If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the following
loads are on: headlamps, high beams, fog lamps, rear
window defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer loads, and
loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the battery.
It does this by balancing the generator’s output and the
vehicle’s electrical needs. It can increase engine idle
speed to generate more power, whenever needed.
It can temporarily reduce the power demands of some
accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to
the driver.
